Anybody know what size the EGR pipe threads are?


Recommended Posts

the EGR tap is a 16x1.5. If the engine doesn't have the EGR hole threaded you use a 9/16 drill bit to get the whole to the right size and a 9/32 is the hole size into the combustion chamber.

 

thank you very much:)

i saw you posted asking if anone had done this before... I've done it several times. Be gentle when you are drilling through into the combustion chamber, go slow. Use wd-40 when drilling and tapping helps it go smooth. Any other question feel free to ask..
